Modeling Of Shearer Cutterhead To Reduce Energy Consumption

The paper deals with the modeling of longwall shearer cutterhead interaction with the coal, in order to study the influence of different limiting factors of the haulage speed, and the cutting regime ensuring optimal energy consumption A computer simulation model is used to draw-up the torque vs haulage speed and the haulage force vs haulage speed dependence diagrams, for different strength of coal and different degrees of bit wear.
